The term "waifu" is a word that is used prevalently in the Manga/Cartoon, and Video-game fandoms. The origin of the word comes from the katakana word for wife; ワイフ

However, Japanese-speakers will never use that word. The real word for wife is 妻 (tsuma/sai).

"Waifu" is used to refer to a fictional girl or woman (usually in Anime, Manga, or video-games) that you have sexual attraction to, and you would even marry.

Remember; "ワイフ waifu" and "妻 tsuma" are completely different. Waifu is a joke word that Anime fans call fictional female characters that they love and would marry if they were real. Your tsuma is your real wife. That is the real Japanese word for wife.
Example of waifu:

"Do you like Camilla from Fire Emblem Fates?"
"I LOVE Camilla! Her large breasts, her curves,... she's my waifu!" 😍
(This guy has sexual attaraction towards Camilla from Fire Emblem Fates. He would even marry her if she was real, he called her his "waifu"

Example of 妻 :

私は今日結婚しました これは私の妻キコです
「I got married today. This is my wife Kiko.」
(A man was married to Kiko that day. She is real, not a fictional character. The real Japanese word for wife was used.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
